Sliding Window Locks (10 Sets) - Adjustable Security Stops for Sliding

In this review the Sliding Window Locks (10 Sets) are examined for homeowners and renters who need a simple, non-invasive way to secure vertical and horizontal sliding windows. The single biggest reason to buy is the combination of an adjustable, drill-free installation and a reinforced aluminum construction that resists deformation, offering lasting security for children, pets and intrusion prevention. The pack includes several locks and keys so a whole home can be outfitted, making it a practical choice for those who want straightforward, visible protection without altering window frames.

Key Features

• Adjustable fit: The locks fit many sliding tracks when the track height is over 0.48 in and the track width is under 0.61 in, allowing use on both vertical and horizontal sliding windows.
• Drill-free installation: No drilling is required; each lock installs with a protective spacer and a screw using the supplied hex key, which makes setup quick and renter-friendly.
• Separated key design: The lock and key are separate to reduce the chance a child or opportunistic intruder can easily unlock the unit.
• Durable material: The thickened aluminum alloy body resists bending and is intended for long-term service in home or apartment use.
• Widened lock body and dual holes: A wider contact area and two fixed holes provide stronger resistance when the window is pushed, improving security at the partial-open position.
• Protective gasket: Each lock includes a washer to avoid scratching or damaging window tracks during installation and use.

Who It's For

These sliding window stops are best for homeowners, landlords and renters who want extra peace of mind without modifying windows permanently. They are useful in family rooms, bedrooms and ground-floor units where preventing unwanted entry and restricting window opening for child safety is important.

They may not be the right choice for custom or oversized tracks that fall outside the size range stated, or for users who require keyed-alike solutions across many locks; measuring the window track before buying is essential to confirm compatibility.

Pros & Cons
